for the whole dataset. In the above the \(\textbf {x}\)  correspondents to the n-dimensional point, \(\omega \)  denotes the parameters that want to be fitted par, and \(f\)  denotes the fitting function (fun). The HEPLike does not provide a minimalizer or a scanner tool as it is not purpose of this type of software. It has to be interfaced with proper scanner tool for example [1]}. Again the user can decide if he/she prefers to perform a \(\chi ^2\)  or log-likelihood fit.
